Subject: Update RI to match latest spec.
X-Git-Tag: OpenSSL_0_9_8m-beta1~22
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=5f409487146a78c4e5619dcb2587a1d9c824f875;p=oweals%2Fopenssl.git

Update RI to match latest spec.

MCSV is now called SCSV.

Don't send SCSV if renegotiating.

Also note if RI is empty in debug messages.
